摘要： In the HSM function, when supporting the file system snapshot function, a differential data volume is required for both a high-speed volume and a low-speed volume. Accordingly, when supporting the snapshot function by using a file system provided by the HSM function, a large amount of differential data volume is required. When the manager gives an instruction to acquire a snapshot, a snapshot management program executes snapshot acquisition processing to acquire a snapshot. In this processing, a snapshot reference relation building processing part copies a file storage location management table, and relates the file storage location management table to the acquired snapshot. Then, the snapshot reference relation building processing part checks a file that is migrated to a file system which does not have a differential data volume. Finally, the snapshot reference relation building processing part creates a link of the migrated file to the snapshot which is acquired previous time.
摘要翻译：在HSM功能中，当支持文件系统快照功能时，高速音量和低速音量都需要差分数据音量。因此，当通过使用由HSM功能提供的文件系统来支持快照功能时，需要大量的差分数据量。当管理员给出获取快照的指令时，快照管理程序执行快照获取处理以获取快照。在该处理中，快照参照关系建立处理部复制文件存储位置管理表，并将文件存储位置管理表与获取的快照相关联。然后，快照参考关系构建处理部分检查被迁移到没有差分数据卷的文件系统的文件。最后，快照参考关系构建处理部分创建迁移文件到先前获取的快照的链接。

摘要： There is provided a file server which is capable of suppressing power consumption of a storage apparatus. When a file sharing program receives a file access from a client, the program makes reference to a mapping table. Then, the program addresses the access to the target file in the volume of a RAID group in which the target file is stored. A coupling-request reception program memorizes a coupling time for each user into a coupling history table. A grouping program applies a grouping to users whose coupling time-zones are similar to each other. A data transfer program transfers, into the same RAID group, data of the files associated with the grouped users, thereby collecting the data of the files into the same RAID group. On account of this, the time-zone during which no access is made to the RAID group (i.e., non-coupling time-zone) can be made longer. Accordingly, a spin-up/down request program makes a spin-down request to the RAID group in the non-coupling time-zone.

摘要： Upon integration of a file system, user identifier recorded in a storage as management data is translated. A file server connected to a storage storing the data of a file system therein has a file system operation unit for managing the file system, a file server operation unit for receiving the access request to the file, and a user identifier translation unit for carrying out translation between first user identifier, which is used by the client and second user identifier, which is recorded in the storage as management data of the file system. Receiving the access request to the file from the client, the user identifier translation unit translates the second user identifier included in the management data of the file that is an access target of the access request into the first user identifier, and the file server operation unit transmits the management data to the client.

摘要： When any file sharing server among a plurality of file sharing servers configuring a virtual file system receives a backup requests from a backup server, the file sharing server that received the backup request searches a file sharing server managing the files to be backed up among the plurality of file sharing servers, and transfers the backup request to the searched file sharing server. The file sharing server that received the transfer of the backup request transfers the backup data to the media server via a connection server.

摘要： A data intermediate server 300 comprises the functions of reading data stored in storage servers ST1 through ST3 and sending the data to a media server 600 according to backup commands received from a backup control device 400 over a local area network LAN4. The data intermediate server 300 and the storage servers ST1 through ST3 are connected by channels that do not permit Internet protocol traffic but only data targeted for backup and control data assigned thereto. As a result, client data stored on the storage servers can be properly backed up while preventing data from being improperly retrieved or leaked.
摘要翻译：数据中间服务器300包括读取存储在存储服务器ST1至ST3中的数据的功能，并且根据从备用控制设备400通过局域网LAN 4接收的备份命令将数据发送到媒体服务器600.数据中间服务器300和存储服务器ST1至ST3通过不允许因特网协议流量的信道连接，而仅通过分配给备份和控制数据的数据来连接。因此，可以正确地备份存储在存储服务器上的客户端数据，同时防止数据被不正确地检索或泄漏。

摘要： A file storage performs control to create a virtual parent file having an identifier capable of uniquely identifying a parent file among storage systems and volumes, and to acquire block layout information of the parent file using said identifier. The file storage creates a virtual parent file in the volume in which the clone file is created, and sets the file as a virtual parent file of the clone file so as to enable creation of a clone file of a parent file that exists in a different volume or a different storage system. Moreover, by combining creating the virtual parent file and switching the identifier of the parent file which is pointed by the virtual parent file, migration of clone files and parent files astride storage systems and volumes is enabled.

摘要： Regarding a method for migrating a file system by copying a file from a migration source to a migration destination and deleting the file at the migration source, a retention of a file in a page (allocation unit of a thin provisioning function) is either suppressed or solved, and two methods are proposed for solving the problems and for enabling migration of a file system in which the increase of utilization of storage capacity is suppressed, wherein one method changes the location of a file prior to performing copying so that the file to be copied next is located in the same page, and another method creates a reverse index table to recognize which block is used by files, thereby enabling to specify the file remaining within a page and copy the same by referring to this reverse index table.

摘要： It is provided a computer system, comprising a server and first and second storage systems. The first storage system stores deduplicated data sharing at least a part of data with other data, shared data shared by a plurality of pieces of the deduplicated data, and first type data representing a type of the stored data including the deduplicated data and the shared data. The deduplicated data is associated with the shared data by a pointer to the shared data, and includes differential data indicating a difference from the shared data. The server creates second type data representing a type of the data stored in the second storage system from the first type data. The second storage system stores the shared data associated with the deduplicate data at a reading position before a position at which the deduplicated data is read in sequential reading and stores the second type data.
